RAIL ANCHOR.

Application filed February 18, 1929. Serial No. 340,747.

The invention relates to rail anchors or anticreepers and seeks toprovide a simple and effective construction which can be economicallymanufactured, and which comprises a clip for gripping one of the railbase flanges and resilient spring means for bolding the clip in positionon the rail.

The invention consists in the features of improvement hereinafter setforth, illustrated in preferred form in the accompanying drawing andmore particularly pointed out in g the appended claims.

In the drawing:

Figs. 1, 2 and 3 are sectional elevation, plan and end veiwsrespectively, of the improved anchor.

The drawing shows a rail base 10, a tie 11, and a tie plate 12. Theanchor clip is preferably formed of a piece of plate steel or like metalof about one-quarter inch in thickness and which is bent to a U-sectionto' provide spaced side portions 13 and a bent connecting edge portion14. The edge portion 14 and parts of the side portions 13 are cut awayto provide notches or seats 15 which fit one of the base flanges of therail for which the anchor is designed. The notches or seats are sodisposed that the clip is adapted to be driven from one side of the railinto gripping engagement with one of the rail base flanges and when inposition on the rail the side portions 13 are disposed in substantiallyvertical planes with the intermediate connecting portion 14 extendingbetween their inner ver- 0 tical edges. Preferably, asshown', the seats15 are so shaped that the edges thereof bear on the upper and lowerfaces of the base flange of the rail but do not contact "with the edgeof the rail flange.

The side portions 13 of the clip extend well below the rail base and arepreferably flared so that the lower portions 16 thereof, which formtie-engaging abutments, are so disposed that when one of them is inengagement with a tie 1 1 as shown in Fig. 3, parts of theanchor areheld spaced away from the tie-plate 1'2.

The clip has a hard driving fit on one of the rail base flanges and isheld against displacement thereon by a part arranged to engage or hookover the other base flange and interposed spring. Preferably these partsare in the form of a cross-arm 17 and a C-shaped spring loop 18. Thecross-arm 17 is preferably U-shape'd or channel-shaped in cross sectionhaving side walls 19 and a bottom wall 20. At one end, the side walls 19terminate in ofl'sets or hooks 21 which are arranged to engage the edgeof the rail base flange and which preferably are provided with lips 22which lap or hook over the edge of the rail flange. The cross-armextends through an opening 23 formed in the inner edge portion 14 of theclip and between the-side walls 13 thereof. At or adjacent its end thecross-arm is providedwith an abutment 24 which engages the outer portionof the spring loop 18. and the bottom wall 20 of the cross-arm is cutaway to form a slot or opening 25 through which the lower portion of thespring loop extends. The cross-arm can be conveniently formed .of asection of plate metal, and in .such case, portions of the side wallscan be bent inwardly and transversely to form the integral transverseabutment 24, as indicated in Fig. 2.

The spring loop 18 is preferably formed of resilient steel rod ofcircular section, is shaped to extend around the edge of the rail flangeengaged by the clip and has down and upturned inner end portions 26 and27 which are adapted to bear respectively, upon the upper and lowerfaces of the base flange. The spring loop is disposed between the sideportions 13 of the clip and its lower portion extends between the sidewalls 19 of the crossarm.

. In the application of the anchor, the spring loop is strained ordistorted so that its end portions 26 and 27 are forced apart and inconsequence resiliently grip the base flange of the rail. Also, theparts are so proportioned that the spring loop is laterally compressedby the engagement of its end portion 26 with the inner edge wall 14 ofthe clip and the engagement of its outer portion with the abutment 24 ofthe cross-arm. Hence, the spring loop serves to press resilientlyagainst the clip and cross-arm and maintain the same in engagement withthe opposite rail base flanges. In applying the anchor, the clip andsprin loop are driven onto one of the rail base anges by the applicationof hammer blows to the adjacent end of the cross- V arm 17. It is notedthat the abutment 24 of the cross-arm and the section of the spring loopengaged thereby, are inclined in such a manner that, as the anchor isdriven onto the rail base, the' pressure of the spring tends to forcethe adjacent end of the cross-arm downwardly and thus press its oppositeend upwardly. Hence, when the other hooked end of the arm clears theopposite base flange, it will snap upwardly into engagement therewith.

The improved anchor is inexpensive to manufacture and can be readilyapplied to the rail. Obviously, any tendency of the rail to creep willforce the lower portion of the clip against the tie and tend to cant itin a vertical plane extending longitudinally of the rail and willthereby increase its grip upon the rail base flange. 'The spring loopand cross-arm will effectually prevent the clip from working loose whenthe clip is rubbed against the cross tie or drawn backthrough theballast by contraction of the rail. To maintain the side sections 13 ofthe clip in spaced relation and connect the cross-arm and spring loopthereto to form a unitary structure when the anchor is ofl' the rail,spacing rivets 28 extend between these side sections through the springloop 18 and above and below the cross-arm 17. The slot or opening 25 inthe cross-arm is of such length that there is a clearance between itsinner edge and the adjacent end portion 27 of the spring loop, so thatthe anchor is adapted to be dri n into griping engagement with beapplied to rail bases of diflierent widths.

Changes may be made in the details set forth without departure from thescope of the appended claims.

Iclaim as my invention:

1. A rail anchor comprisin a clip and a retaining spring, both adaptedto grip one of the rail base flanges, and means arranged to engage theother base flange and hold said spring in position.

2. A rail anchor comprising a clip and a retaining spring, both adaptedto grip one of the rail base flanges, and a cross-arm having an oflsetadapted to be held in engagement with the edge of the other base flangeby the spring.

3. A rail anchor comprising a clip and a retaining spring loop for theclip, both adapted to grip one of the rail base flanges with an innerportion of the spring loop engaging the clip, and a cross-arm havingabutments at its ends for engaging the outer portion of said s ring loopand the edge of the other base fl zinge respectively. p

4. A rail anchorcomprising a clip and a retaining spring loop for theclip, both adapted to grip one of the rail base flanges with an innerportion of the spring loop engaging the clip, and a cross-arm havingabutments at its ends for engaging the outer portion of said spring loopand the edge of the other base 6. A rail anchor comprising a clip of U-.
